Shopping guidance from Toledo Indoor Garden. Prices, availability, shipping rates, weights, and dimensions are verified during checkout.

NPK RAW Phosphorus contains 61% water-soluble phosphate along with approximately 9% ammonium nitrogen, providing one of the cleanest and most concentrated phosphorus sources available.

Phosphorus is the energy element in plant nutrition, playing a critical role in root growth, energy transfer, and reproductive development.

The supplement is especially useful during the first two to three weeks after planting when strong root systems are being established, and again during flower and fruit production when energy demands peak.

Fully soluble and compatible with all nutrient programs in soil, coco, and hydroponic systems.
